SPRAYING=NOZZLE.

SPECIFICATION forming part of Letters Patent No. 511,729, dated December26, 1893.

Application filed April '7, 1893. Serial No. 469,454. (No m del.)

To all whom it may concern:

Be it known that I, WILLIAM L. DEMING, a citizen of the United States,residing at Salem, in the county of Oolumbiana and State of Ohio, haveinvented certain new and useful Improvements in Spraying-Nozzles; and Ido hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

My present invention relates to apparatus for spraying. trees, plants,&c., for the purposes of treating them with the various wellknowninsecticides or disinfectants, and has for its object the production ofa cheap, simple, and effective nozzle designed, arranged and adapted toapply such solutions to tender as well as hardy shrubbery, at the sametime providing for a wide range of distribution of the spraying liquidthus used.

The invention will be hereinafter described and particularly pointed outin the claims.

In the accompanying drawings which form part of this specification, andin which like letters indicate like parts wherever employed, Figure 1,is a side elevation, and Fig. 2, a longitudinal central section of myimproved nozzle, detached.

Reference being had to the drawings and letters thereon, A, indicatesthe body of my invention, preferably cast from brass as also are thebalance of the parts, and provided with a longitudinal compressionchamber 13, closed at one extremity by an end wall co perforated as atb, for a purpose that will hereinafter appear.

To the side of body A, and integral therewith, is an enlargement or webof metal O terminating in a projecting screw-threaded coupling 0, forconnection with a hose or force pump; while said web 0 is intersected byan oblique channel D,connecting and establishing communicai ion betweenthe coupling 0 and chamber B. Body A, at its opposite end is providedwith an external screw-thread d, adapted to receive a correspondingthread 6 on the inner wall of cap E, said cap serving as a covering forchamber B, and being provided with a flaring orifice F in its outerface, and a similar one fin its opposite face, the two combining toconstitute a discharge port as shown in Fig. 2.

Resting in aperture b, and within chamber B, is located a longitudinallyreciprocating and axially rotatable spraying and cleansing piston,consisting of a shaft or stem G, provided with a push button g at itsouter extremity, its opposite end being conical as at H. At the base ofthis cone, is formed an integral collar or enlargement h equal in itsdiameter to that of channel B, and having cut in its periphery a spiralgroove I, forming the only source of outlet for the spraying liquid;while at a point in chamber B, on the opposite side of inlet channel D,is arranged a second collar 2', similar to that marked it with theexception only of the peripheral groove, and between this latter collarand end wall a is interposed a packing ring J of rubber or othersuitable material.

The operation of this improved nozzle is as follows: A suitable sprayingmixture having been introduced under pressure through channel D, tochamber B, exerts its force upon the walls of said chamber and upon theinner surfaces of the collars h, and 'i, but with unlike effect,inasmuch as, the peripheral screw I affords a vent or outlet through theformer thus reducing the pressure in that direction, while its fullforce and effect are received by the latter, tending to keep it normallyseated as shown by Fig. 2. The spiral channel I, through which theliquid is then forced serves to impart thereto a regular, rapidrevolving motion in which condition it is ejected from the doubleorificesf, F, by meeting the edges of which it is further disintegratedand reduced to fine spray. Should the discharge nozzles become cloggedby continuous use of heavy solutions or those which are not clear, suchfor instance as mixtures embodying lime; it is only necessary to elevatepiston G by pressure applied to button g, by which movement cone II willbe caused to enter the discharge orifices in cap E for the purpose ofcleansing them of sediment or foreign matter.

Having thus described my invention, what I claim is- 1, In a sprayingnozzle, the combination with a main compression chamber having a sideinlet or supply channel, and a reciproeating rotatable piston located insaid chamher having a spiral. outlet in its periphery, substantially asdescribed.

ICO

spirally grooved head with its opposite end v protruding from saidchamber, a conical distal end on said rod registering with the dischargeorifice, and a disk located near the opposite end of the rod,substantially as described.

In testimony whereof I subscribe my signature in presence of twoWitnesses.
